This invention relates to work supports for fastening inserting machines and is illustrated herein as embodied in a machine of the type disclosed in Letters Patent of the United States, No.

1,904,313, granted April 18, 1938,01@ an application filed in the name of Charles Frederick Reginald Jeavons.

Heels .which have metallicl tips attached to their rear portions are often provided with top 1 0 lifts which are cut out to receive the metal tips so that the upper surfaces of the metal tips will form part of the tread surfaces of the heels. These metal tips are provided with perforations through which the fastenings are inserted and in order that the metal tips and the top lifts of vthe heels will form unbroken tread surfaces and also to prevent the `metal tips from projecting beyond the edges of the heels it is necessary that the metal tips be held closely in contact with the 20 cut-out portions of the top lifts during the fastening rinserting operation. lt hasbeen found inlpractice that small portions orY burrsarefrequently left on the edges of the metal tipsl of such a nature that considerable force or pressure is tact with the edges of the top lifts.

1n View of the above, it is an object of the present invention to provide a Work support for fastening inserting machines of such a character as to facilitate the positioning of metal tips and `unattached heels prior to the fastening' inserting operation. With this object in View a feature of the invention resides in means whereby the machine operator may conveniently lcause a metal r tip assembled with a heel to be pressed firmly into contact with the top lift of the heel in position for and immediately prior to the driving of the fastening.

As illustrated herein a novel work support is provided having work supporting means for moving the Work into engagement with the Work engaging face of a fixed presser plate or work abutment yand work grippingrneansmovable transversely of the Work support to position the work V in engagement with an edge gage rigidly secured to the presser' plate. Mechanism is provided in the form of a treadle forelevating the work support and for moving the Work gripping means transversely of the support and preferably the ysame tread-le is utilized to increase the transverse pressure of the gripping means to cause the metal tip and heel to be pressed closelyV together after the work has been moved into engagement with the` presser plate. A further feature of the invention resides in means for adjusting the initial required to position the metal tips closely in conposition of the work gripping means in accordance with the size of heel to be operated upon. With the above and other objects and features in View the invention will now be described in connection with the accompanying drawings and GQ will bepointed out in the claims. In the drawings, v Fig. 1 is a side elevation of a fastening inserting machine provided with a Work support constructed in accordance with the present invention; v

'Figv 2 is a side elevation on an enlarged scale of the work support shown in Fig. 1; and a Fig. '3 is a plan view of a heel with a metal tip attached thereto and illustrating the position of '(.Q the heel with respect to the fastening inserting driver and edge gage during the fastening inserting operation. l The invention'is herein illustratedas applied to a fastening inserting machine of the type dis- 7,5 closed in the application hereinbefore referred to and reference may be made to the said application for a more complete disclosure of parts not fully described herein. The illustrated machine is provided with a main frame lO'carrying at its upper end a head 12 and with a secondary` column 14 carrying the work support of the present invention indicated as aV whole at 16. The head 12 carriesy a cam shaft 18 from which the various partsof the machine are operated. A driver'bar 19 carrying a driver 23 is moved upwardly by means of a lifting cam (not shown) which engages a projection on the driver bar 19. A spring-pressed lever 25 fulerumed at 27 to the head of the machine and connected by a link 29 90 with the driver bar 19 forces ythe driver bar 19 and driver 23 downwardly as the cam passes out from under the projection on the driver bar 19 thus driving a fastening into the Work. The kwork support is arranged to clamp the work against a presser plate 20 carried by the head l12 of the machine. vThe work support is moved downwardly from a pressure applying position after a fastening has been,` inserted into the work, to allow the work to be fed by the operator and upwardly into a pressure applyingv position to clamp thevvork against the presser plate 20 by suitable release mechanism, for example as disclosed in Letters Patent of the United States No. 265,227, granted September 26, 1882 on an application of Louis Goddu, also driven from the cam shaft 18v by means of la cam 22. The cam 22 is connected with, a horn depressing lever 24 havingits fulcrum at 26 and connected at 28 with the lovver end of a work supporting 110 -kclamping pressure has been applied to the work.
